Mymemory.com appears to be a great place to find exactly what you need in term of memory cards and memory sticks. A great feature of this company mymemory.com is that you automatically gain 2 years minimum warranty which offers you some covers if anything goes wrong.
The website itself mymemory.com is directly aimed at memory style products therefore they are made to a very high standard which means you can buy in confidence that you’re buying quality.
Unlike other websites mymemory.com gives you all the choices which are available to you for the Sony PSP and offers you many various PSP memory sticks which suit you best. I found this to make things so much easier than having to read up on every memory stick which I found with other websites.
I hope this website has been helpful and that you find the exact PSP memory sticks which you are looking for on this website.
